Calculation of loss and gain of components in parentage and altered rocks during metasomatism, reveals that, in rubification and afforestation belts, the components brought in were K〓, CO〓, H〓O, and the components brought out were SiO〓, Ca〓 and Na〓, implying that the early ore-bearing hydrothermal fluids were rich in CO〓 and H〓O. SiO〓 brought out from potassic and chlorite alteration zones could serve as the main source for SiO〓 necessary in the formation of quartz veins, of silicification and of bericitization at shallow depth.
说明早期成矿流体为富含CO〓、H〓O等的碱性流体,其中钾化、绿化带中带出的SiO〓等是浅部石英脉、硅化、绢英岩化中硅质的主要来源,带出的Ca〓与成矿流体中的CO〓结合形成碳酸盐化,带出的Na〓则在浅部形成钠长石脉。
